Question

I was wondering if anyone has run into the issue that I am experiencing with my current ASR engagement while running the ASR DP Throughput Test for VMware to Azure:

Error in uploading files. Failed to calculate achievable throughput.

Possible reasons:

1. STORAGE_COMMUNICATION_ERROR. Unable to communicate to Azure Storage blob. Check network connectivity to Azure and if bandwidth from on-premises to Azure is very low.

What’s got me scratching my head is the Error Output in the command line vs. Error Output the logs. The snippet from the logs show the top error repeated several times in the same way prior to the last error which generates the error in the CLI screenshot
above):

But that’s not all….. the DP throughput test actually puts vhds in Azure to the SA as it does its test (visible in Azure Storage Explorer while test is running), but continues to fail with the same output regardless of machine (physical or virtual) that
I run this tool on. The customer I'm working with claims that their bandwidth pipe is 50MBps, however while looking at their Cisco ASA dashboard, we see the DP consume no more than 50Mbps or 6.25MBps.

I am unable to advise my customer on throughput issues, or planning correctly beyond the report generated from the profile of the Deployment Planning Tools output.
